What exactly are you trying to backup? User mbox files found under /var/spool/mail/*user_name* or sendmail's spool files under /var/spool/mqueue? Are you moving the spool to another box or just upgrading sendmail?If upgrading the daemon you can leave them alone...any way you do should be fine,you can even tar/bzip2 them...just make sure to preserve onwnershp of the files.Hope this helps.
